Crankshaft and camshaft measuring instruments

​
​

The DD series balance measuring machines measure crankshafts in their material state and calculate the dynamic balance center, leading to the optimal machining position of the center hole, which has a significant impact on the dynamic balance. This is a completely different concept from conventional balance measuring machines and provides innovation to the crankshaft machining line.
The GDBV-2 series of accuracy measuring machines can measure the accuracy of both crankshafts and camshafts with a single unit. It is possible to handle multiple workpiece types with a simple program change.

Komatsu NTC technology

High productivity requires automation and flexibility for easy, high-precision measurement, and is infused with the flexibility we have developed in our powertrain production lines.

Automotive industry machining line

Our extensive experience with crankshaft machining lines enables us to propose the optimum chucking method for stable measurement.

High-speed processing for the line

High-precision, high-speed laser measurement and calculation data output processing for the first time in response to the cycle time of crank lines.

Measurement, recognition, and processing

Yield rate improvement processing technology by counterweight laser measurement method born from Komatsu NTC's innovation.
